Commericalism of literary fiction.

The publishing world is strange.  The Literary writers hate the genre fiction writers because genre fiction is purely entertainment.  Any student of a collegiate writing arts program can vouch for that.  However, it was surprisingly (to me anyhow) that at a horror convention, I was talking to a representative of a small press horror editor – and they appeared to hate literary fiction because it isn’t as marketable.   And commericalfiction prides itself on aspects of writing (many elements opposed to what we are taught at University) that sell books.  Note: I understand that it may have been this particular editor’s bias.  Regradless,  I find it strange that as a fiction writer we are supposed to create “marketable literary fiction” when in the publishing world they sometimes appear as polar opposites.
